IMPRCVEMENT IN CARBURETERS.

Specification forming part of Letters Patent N o. 146,082, datedD.cember 30, 18,73; application filed i September 15, 1873.

To all whom fit may concern:

Be it known that I, J. BALDWIN LYMAN, of Rockford, in the county ofWinnebago and State of Illinois, have invented a new and usefulImprovement in Gasliachines; and I do hereby declare that the followingis a full and exact description of the same, reference being had to theaccompanying drawings and to the letters of reference marked thereon.

Figure l is a side elevation of my improved apparatus, showing one ofthe air-tanks in section. Fig. 2 is a plan or top view, and Fig. 3 is aside elevation, partly in section, through the gasoline-tank, andshowing the manner in which the air is injected therein.

Similar letters of reference denote corresponding parts Whereverused.

The invention relates to a novel construction of apparatus andarrangement of its parts for forcing atmospheric air into and throughgasoline or other volatile oil, and for regulating the pressure and flowof the resultant illuminatinggas to the burners, as hereinafterexplained.

For the purpose of holding the gasoline or oil, a suitable tank, A, isprepared and placed outside of the building for the sake of safety, withan opening at a for filling, said opening being provided with anysuitable cover or stopper. Said tank is also provided With a pipe orpipes, b, for conveying the gas to the burner or burners Alocated in thedifferent rooms of the house. There are also other pipes, c c, reachinginto this reservoir and running to or nearly to the bottom, and providedon their lower ends with enlarged chambers C, preferably made ofcircular form, as shown. This chamber is provided With numerous smallperforationsin the top and on its periphery for the purpose ofdistributing the air through the gasoline, as hereinafter explained.These pipes, one or more in number, reach from the tank to and throughthe Walls B of the house into any suitable room, and inside of saidWalls and Within reach of the operator these continuous pipes areprovided With stop-cocks C for excluding the air when necessary, ashereinafter explained. These pipes lead still farther, after passing thestop-cocks, and end in an air-chamber, D, or reservoir, so arrangedthat, by its connecting-pipes and stop-cocks,

has tubes ere, preferably made upright, one or more in number, which arealso provided with stop-cocks, for purposes herein afterexplained.

In cold Weather, if desired, tubes can be provided and connection madewith a Warm room,

thus filling the gasometers With heated air.

This chamber E has also in part) flexible tubes or pipes F leading tothe gasoineters or air holders G G', one or `more in number. Metal pipesmay be used in place of the ilexi-` ble, if preferred, bypassingtheinoutside of the receivers, and causing them to enter at the bottomof the fixed cylinders G. The gasometers or air-receivers can be placedbeneath the floors of the house, inthe cellars, and out of the Way, orcaube placed out of doors, Wherever desired. Inside of these stationarytanks are movable air-holders G', madesimilar to the ordinary gasometer,but containing atmospheric air in place of coal-gas. H H are Windlasses,operated by means of crank h, and provided with cords running overpulleys I 011 the frame-Work of the air-holders, and connected with the:movable gasometers or holders G', as shown. I

The operation is as follows: When the gas is to be made, after thegasoline-reservoir is filled, and Water-packing placedV at g in thegasometer or air-receivers, the stop-cocks are opened in the secondaryreservoir for admit-` f ting air, the crank is placed on the Windlass,and the movable inside holders G', which are open on the under side, areraised up, forming a vacuum between the head and Water, which causes theair to rush in through the opened pipes in the secondary reservoir.While the gasometers are being raised, `either the stopcock C or thestop-cock d must be closed, otherwise the vapor pressure in the gasolinetank A might force the fluid gasoline up i through the pipes c cinto the`air-chamber D. These cylinders or gasometers ca-n be raised, by anywelhknown means, `to create this vacuum. Then the air-holder is lled,the supplycocks e in the secondary reservoir are closed, the air iscontained in the receiver, which can be Weighted as heavily as required,to obtain sufficient pressure. The stop-cocks d leading to the mainreservoir are opened7 as Well as the stop-cocks C' in the pipes runninginto the gasoline-reservoir. The stop-cock in the pipe b, leading to theburners, may be closed until it is necessary to light the gas. When thegas is lighted, or the stop-cock turned at the burner, the pressure onthe air-holders G forces the stored-up air through the differentconnecting-pipes down to the bottom of the gasoline, or other volatilefluid, spreading it through the entire mass of said fluid. The deliveryof the air into the gasoline, through the very minute openings in theterminal chamber C, also prevents the rising and falling of the fluid inthe tube, and insures a steadyr light, and, in practice, has been foundpreferable to the said delivery through an open tube.

Itis important in the manufacture of gas from gasoline that the supplyof air to the gasoline-tank should be easily regulated, so as to securea steady and uniform light. This object I accomplish by Weighting thegasometer, to secure the requisite pressure, and by the use of thestopcocks connected with the chambers D and E, and by the delivery ofthe air into the gasoline through the minute open-` ings in the terminalchamber C, before mentioned. No matter what the amount of pressnreexerted by the gasometer, the How of the atmospheric air into andthrough the gasoline,

and to the burners, may be regulated, through the various stop-cocks, atWill, and With the greatest precision.

Having thus described my invention, What l claim as new, and desire tosecure by Letters Patent, is*

l. The perforated air-chamber C, arranged Within the tank A, asdescribed, in combination with the air-chamber D, intermediate be tweenthe receiver G and chamber C, substantially as and for thepurpose-described.

2. The secondary or supply chamber E, provided With the supply andoutlet pipes, as described, in combination With the holder G G for thesupply of the air to said holder, and for the transmission of the sameto the storing-chamber D, as set forth.

3. The combination of the holders G G', supply and storing chambers Dand E, tank A, and terminal chambers C, all arranged and operatingsubstantially as and for the purpose set forth.

4. The air-chamber D in combination with the receivers G G', tank A, andconnecting and supply pipes and their respective stopcocks c c', d d, ec', and F, arranged and operating substantially as and for the purposedescribed.

This specification signed and witnessed this 11th day of September,1873.
